One of the reasons I am never step-parenting again is because the bio parents (the ones in my experience) have out of this world expectations due to entitlement and delusions of grandeur. 

One time, I was sick with Covid and not even past day 5 (when the cdc recommends you can return to work, public with mask, almost normal), the disneyland dad blew up my phone (should have ignored but I thought he was dying or something) and asks if his kids can come over (he's still at work) to our house.
